ELEVATOR-SHAFT.

SPECIFICATION forming part of Letters Patent No. 503,392, dated August15, 1893.

Application lerl March 23, 1893. Serial No. 467,246. (No model.)

To @ZZ whom, it may concern.-

Be it known that I, GEORGE VAssAR, Jr.,a citizen of the United States,and a resident of New York, in the county of New York and State of NewYork, have invented certain new and useful Improvements inElevator-Shafts, of which the following is a specification.

This invention relates to elevator shafts in buildings, the Object beingto construct such shafts at a comparatively small cost, of lightmaterial and which will be durable, strong and tire proof.

The invention, therefore, consists in suit able metal uprights, bracedat desired points and having the walls formed of wire lathing or nettingto which a iinishing plaster may be applied, as hereinafter describedand claimed.

I will describe an elevator shaft embodying my invention and then pointout the novel features in claims.

In the accompanying drawings Figure l, is 'a sectional plan view of anelevator shaft em bodying my invention. Fig. 2, is a side elevationthereof with a portion Of the plastering removed and with a portion ofthe wire lathing removed. Fig. 3, isa detail on an enlarged scale of oneof the corner risers and a portion of lathing. Fig. 4, is a detail on anenlarged scale showing a means of attaching a brace.

Referring by letter to the drawings A designates the corner risers.These are of iron and are preferably l. shaped orsubstantially so incross-section. Metal lathing A', forms the inner and outer walls of theshaft and is shown as extended from One corner riser A to anotherexcepting at the front which has the door Ways or opening. At this partIprovide metal risers A2. Intermediate metal risers A3 may be arrangedintermediate of the corners. These intermediate risers are shownI-shaped in cross-section but I do not limit myself to any particularshape. The wire lathing Or netting maybe secured to the several ri'sersin any desired manner. The adjacentL risers are preferably braced, onerelatively to the other by means of iron crossbraces ct, which may befastened to the risers in any desired manner. In Fig. 4, I have shown abrace d as secured to the riser, by means of bolt a.

Suit-able plastering CL2 is applied to the lathing or netting A', and asthe plastering is applied portions of it will project through the meshesof the lathing and key to the inner side.

represents the elevator posts usually pnt in the shaft with theelevator.

It will be seen that this elevator shaft may be constructed with greateradvantage as to space than those formed Of brick or similar material andyet will be tire proof.

Having described my invention, what I claim isl. In au elevator shaft,the combination Of the metal corner risers L shaped in cross-section,the intermediate risers, the inner and outer walls of metal lathing ornetting secured to said risers and the plastering, substantially asspecified.

2. In au elevator shaft, the combination Of the metal corner risers, theintermediate risers, the metal cross-braces, the inner and outer wallsof metal lathing secured to the risers, and the plastering,substantially as specified.

Signed at New York, in the county of New York and State of New York,this 17th day of March, A. D. 1892.
